February 16, 2022, 2 p.m. room 228, dr hab. Piotr Artiemjew, prof. UWM, University of Warmia and Mazury, Olsztyn, “Real Toy Decision Systems Generator for Presenting Data Mining Algorithms” (the lecture will also be available online by invitation)

Abstract: Probably every data scientist has come across Quinlan’s toy decision system (the decision problem of playing tennis), which has become a popular system for presenting toy examples of ideas for new data science algorithms. In this work, we address researchers who would like to use a variety of meaningful, real-world data to demonstrate their algorithms using toy examples. We propose a novel tool for generating toy decision systems from original decision systems addressing real decision problems. Would you like to present toy examples of your methods on little meaningful real data, this tool is for you. The toy systems are generated using a granulation techniques and feature selection methods. The resulting toy systems represent the essence of real decision systems, they provide meaningful data that can be used to demonstrate the action of your own data science methods.
